The terrorism bomb blasts last week in Brussels “are a somber reminder of the difficulty of preventing attacks against transportation infrastructure such as airports and metro or bus stations,” notes catastrophe risk modelling company Risk Management Solutions (RMS). “As security at military bases, embassies and other government facilities increases, there has been a trend among terrorists in targeting softer targets such as public transportation infrastructure,” notes observations released Friday by RMS, which provides models and software to help financial institutions and public agencies evaluate and manage catastrophe risks.
